<p>This module is able to find a version of DCMTK that does or does not export
a <code class="docutils literal notranslate"><span class="pre">DCMTKConfig.cmake</span></code> file. It applies a two step process:</p>
<ul class="simple">
<li><p>Step 1:  Attempt to find DCMTK version providing a <code class="docutils literal notranslate"><span class="pre">DCMTKConfig.cmake</span></code> file.</p></li>
<li><p>Step 2:  If step 1 failed, rely on <code class="docutils literal notranslate"><span class="pre">FindDCMTK.cmake</span></code> to set <code class="docutils literal notranslate"><span class="pre">DCMTK_*</span></code>
variables details below.</p></li>

This requires official DCMTK snapshot <em>3.6.1_20140617</em> or newer.</p>
<p>Until all clients update to the more recent DCMTK, build systems will need
to support different versions of DCMTK.</p>
<p>On any given system, the following combinations of DCMTK versions could be
considered:</p>
